one track howl solution
Here's something I posted a while back. I did this to my 05 venture & it's really worked great for thousands of miles. Maybe Cat's "Quiet Track" patent will expire soon so Yami can start using them on their sleds in the US.
Here's an update on track howl,
After extensive experimenting w/ a fix for this maddening noise, I finally settled on the following solution:
I replaced all 6 wheels w/ polaris (the older, smaller ones). I installed 116 woody's signature(flat topped) 1.325" studs in two rows, between every bar, in line w/ the inner wheels, w/ a 1" thin washer under the head of each one (inside the track) causing them to protrude approximately 1mm above the track. This basically mimics cat's patented "quiet track", which uses the molded in rubber wedges to support the wheels in the inter-lug area, thereby reducing the vibration caused by the "washboard effect" of the wheels slapping the fiberglass bars in the track. The stud heads stiffen this interlug area & support the wheels, reducing the vibration.
Here are the results of my experimenting:
DEAFENINGLY LOUD- stock plastic wheels, especially after the slides wear slightly, putting more pressure on the wheels. Earplugs aren't much help since the low frequency sound travels right through the skull.
QUIETER- Installing polaris wheels. Many have had decent results doing this.
MUCH QUIETER!- Adding the studs as dicussed above. Note: simply adding the studs w/ out the washers will probably make the noise worse, since they countersink slightly, causing the wheels to dive even deeper between the lugs. You need the washers to raise the heads.
QUIETEST- Removing all 6 wheels. I did this and enjoyed the silence for about 300 miles. Of course you have to stay in the powder for the slides.
So far so good after a couple thousand miles.
Sure would have been nice if Yamaha would have addressed this issue. Hopefully this info will save some peoples hearing. Great sled overall.
